July 8, 2020 – Dry weather with seasonably warm temperatures for the week, with high temperatures in the Valley reaching around 100 for the weekend.
The upper level pattern becomes fairly flat today as ridging begins to rebound in the wake of a departing trough. The Delta breeze has weakened significantly, with current temperatures 4 to 7 degrees warmer at 2 am than the same time yesterday.
Northerly winds have developed over the northern Sacramento Valley, and this has kept Redding at a warm 78 degrees, 10 degrees warmer than yesterday.
Afternoon highs will be a few degrees above normal levels today. Delta flow will be a little more this evening, though, as a weak shortwave passes through. This will bring a little more cooling overnight into early Thursday.
Afternoon highs will be maybe a degree or so warmer, with little change into Friday. Four Corners ridge expands further into the area by Saturday, with much of the Valley reaching highs around 100.
Extended Discussion (Sunday through Wednesday)
Our quiet weather is going to continue into the extended period. An upper level trough will be pushing east through the PacNW but wont have much impact on our weather here. It will bring some increased onshore flow but overall winds will be weak except through the Delta.
Weak troughing is then expected over the region into next week but won’t cool our temperatures a ton. Highs throughout the period will be just a bit above average.
